My Briggs and Stratton power generator wasn't used for 3 years. Trying to start it again, lead to some problems. The video will show you the true story and the solution. The first problem was, that it lost some fuel - the fuel pipe was broken. In good hope I tried again to start it, but it stopped within seconds. A check of the spark plug to find a very dirty one. After cleaning the spark plug, the engine ran, but only for a few seconds. It lost a lot of fuel and stopped again. The fuel was coming out of the air horn because the float chamber had an overflow. The video will show you how to open the carburetor and how to clean it.
